We will have to move up to do that. Not sure of the cost. There are a lot of teams ahead of us needing a QB. History says 1-2 will work out. Not many years 3+ QB's have made an impact in their first few years.
Cleveland
Denver
NY Jets
Arizona
They ALL NEED A QB now and will draft one.
NY Giants
Miami
Cindy
Washington
Chargers
They are in the market and might pull the trigger early.
To get the #5 QB we would need to trade up. Rosen, Darnold, Jackson, Allen, Mayfield, Rudolph and Finley, If one of these guys is left, is he really the franchise? Is he worth losing a 1st or 2nd for Who drops to #21. Would you bank the 2018 season on him?
I say draft whoever falls or trade up if you absolutely believe this is your franchise QB. Then pick up a Vet who will throw downfield. As much as I want to blame Dennison, TT leaves plays all over the field. His avg time of release is 3.1 seconds. (dead last in the NFL) No coordinator can appear competent with that.
I'd love Cousins, but he is too costly and will set the team back. Smith and Keenum seem to be the most viable options. If McCarron or Chase Daniel become available, they might be worth a shot. We are not in a great position to find our franchise QB in this draft, unless we pull a Texan sized move or Chief move and trade the farm to move up to the 4 spot. 3 or 4 QB's could go in the top 10 in this draft.
